Early Ordovician to early Silurian forearc accretionary processes in front of the Selety–Stepnyak arc in the Kokchetav area, northern Kazakhstan: implications for continental growth in the northwestern Altaids
In the Kokchetav area, a late Neoproterozoic to early Palaeozoic metamorphic, ophiolitic, and volcanic–sedimentary complex provides important insights into crustal accretion in the northwestern Altaids. We car...

Genesis and metallogenic characteristic of Dongnan Cu–Mo deposit associated granitoids: LA-ICP-MS zircon U–Pb dating and isotope constraint from Zi**shan ore field in southeastern China
The Dongnan Cu–Mo deposit, located in the southeast of the Zi**shan ore field (the largest porphyry–epithermal system in Southeast China), represents the complex magmatic and metallogenesis events in the regi...

Meso-Neoproterozoic Multiple Rifting and Magmatism in the North China Craton
formed around 2.50 Ga. A 2.50–2.35 Ga period involved a time of tectonic quiescence, and then an important orogenic epoch, i.e., the period of Hutuo Orogeny. The tectonic processes of rifting, subduction and ...

Origin of the Low δ18O Signals in Zircons from the Early Cretaceous A-Type Granites in Eastern China: Evidence from the Kulongshan Pluton
The origin of low δ18O signals in zircons from the Early Cretaceous A-type granites in eastern China has long been disputed. It is uncertain whether the 18O-depleted features were inherited from high-temperature ...

Older orogens cooled slower: new constraints on Orosirian tectonics from garnet diffusion modeling of metamorphic timescales, Jiaobei terrain, North China Craton
Metamorphic timescales harbor crucial information for quantifying lithospheric processes and identifying tectonic regimes. The Orosirian Period is known for global orogenesis during 2.1‒1.8 Ga that possibly si...

Renewed profile of the Mesozoic magmatism in Korean Peninsula: Regional correlation and broader implication for cratonic destruction in the North China Craton
Widespread Mesozoic magmatism occurs in the Korean Peninsula (KP). The status quo is poles apart between the northern and southern parts in characterizing its distribution and nature, with the nearly absence o...

The genesis of Archean supracrustal rocks in the western Shandong Province of North China Craton: Constraints on regional crustal evolution
Archean greenstone belts are supracrustal sequences, the lower part of which is usually composed of voluminous ultramafic-mafic volcanics. Intermediate and acid volcanic rocks increase in abundance towards the...

Late Mesoarchean crust growth event: evidence from the ca. 2.8 Ga granodioritic gneisses of the **aoqinling area, southern North China Craton
Recently, more attention has been paid to Precambrian magma events and crustal growth of the North China Craton (NCC), accompanying with controversy in activity stages and dynamic mechanism. In this study, we ...

Secondary phosphatization of the earliest Cambrian small shelly fossil Anabarites from southern Shaanxi
Biomineralization may have an extremely long evolutionary history since the Paleoarchean, while the widespread biomineralization among metazoan lineages started at the earliest Cambrian. However, the primary m...
